build fails on Windows on 0.7/1.0 #56
Comments
|
The root cause seems to be JuliaPackaging/WinRPM.jl#150 |
|
Is there any solution for this error? |
|
see JuliaPackaging/WinRPM.jl#157 I still need to create a test for the solution, need to find some time to do so... |
|
For what it's worth, I'd also be grateful to see a solution to this issue. Thanks! |
|
please see JuliaPackaging/WinRPM.jl#157

In order to build Cbc on windows 10, should I install an earlier version of Julia? |
|
Cbc works on Julia 0.6.x under Windows. |
|
I found a solution for that. The error is about finding a file in WinRPM package so when you change the file name |
|
The PR mentioned above does solve that.

"mingw64-libstdc++6-8.2.0-2.1.noarch.cpio" to
"mingw64-libstdc%2B%2B6-8.2.0-2.3.noarch.cpio" in
C:\Users<user>.julia\packages\WinRPM\Y9QdZ\cache\2 folder it builds fine.
But we still need a generic solution.

I am new in github and julia. So, what does PR mean and how can I apply? |
|
A PR is a Pull Request. It is a way to merge code changes and keep track of all the changes. |
|
I worked around the build issues on Windows (with help from the above - thanks). However, I now get a runtime Access Violation Exception, see error below (tried on two different machines). Is anyone else experiencing this? Error:

@Plug11 can you provide a reproducible example? |

Hi, sorry for the delay, the problem seems to be an interaction between Clp and Cbc. If I include ### When we load the Clp package, it causes Cbc to crash
### Comment the following line and the crash does not happen
using Clp
using JuMP
using Cbc
m = Model(solver = CbcSolver())
@variable(m, 0 <= x <= 2 )
@variable(m, 0 <= y <= 30, Int)
@objective(m, Max, 5x + 3*y )
@constraint(m, 1x + 5y <= 3.0 )
print(m)
status = solve(m)
println("Objective value: ", getobjectivevalue(m))
println("x = ", getvalue(x))
println("y = ", getvalue(y))

That makes sense. Clp and Cbc both have dependencies in common that are currently provided by different (and possibly conflicting) dlls. The fix is likely to move Cbc to BinaryBuilder. @juan-pablo-vielma has been working on this but ran into technical issues that are blocked by missing functionality in BinaryBuilder. |
|
The missing BB functionality was just added and the windows bug for Clp seems to be resolved, so it looks like I am back on track with the move to BB 🤞 |
|
Great, good to hear we have a solution on the way! |
|
@Plug11 can please try if these versions of Clp/Cbc work on your system |
|
Hi @juan-pablo-vielma, thanks very much for this! I installed and ran the test script and it now runs through and gets the result without crashing. I did get some warnings which I post below in case they are of interest. |
seems to be looking for
mingw64-libstdc **%2B%2B**6-7.2.0-3.2.noarch.cpioin stead of
mingw64-libstdc**++**6-7.2.0-3.2.noarch.cpio.Encoding issue I presume?
